BOTTLE-STOPPER.

SPECIFICATION forming part of Letters Patent No. 251,838, dated January 3, 1882.

Application filed J 11110 27, 1881.

To all whom it may concern:

Be it known that-I, JE'rHRo B. CRAWFORD, of Rochester, Monroe county, New York, have invented a certain new and useful lmprovgment in Bottle-Stoppers, and I do hereby declare that the following is a full, clear,and exact description of the same, reference being had to the accompanying drawings, in which-- Figure 1 is a sectional elevation of the top of a bottle with my improvement applied thereto. Fig. 2is an elevation at right angles to Fig. 1. Fig. 3 is a plan of the stopper. Fig. 4 is a detail view, showing the screw, and acrosssection of the coils of wire which engage with the threads thereof.

My improvement relates to that class of hot tie-stoppers in which a screw is used for forcing the stopper downward to pack it in its seat.

The invention consists in-the employment of a screw fast to the stopper-cap, and a bail or yoke having coils formed thereon, which embrace the fixed screw and engage with the threads and form the nut through which the .Screw moves, thereby avoiding the necessity of beer-bottle. B is the common neck'wire, and

G is the bail or yoke, pivoted in the neclewire, as usual. D is the metallic stopper-cap, and Edit} packing girrg,ormdiglr, of TH bber, lt. ,cgrk, dranydthel 'table triaterial. The

is formed with a pro ecting milled edge, a, by which it may be seized and turned with facility. It also has a vertieal flange, b, which, when the cap is forced down, overlaps the top edge of the bottle and centers the stopper, also screens or incloses the packing, as shown in Fig. 1. 1n the bottom of the stopper isformcd a cavity or seat, in which rests the packingdisk E, the latter being simply a thin, plain disk, which fits closely to thecap. In the part of the cap which tits directly over the rim of the bottle is a groove, 0, which, when the stopper is pressed into place, allows the packing tosink' therein,therebyconformingto theshape of the rim and increasing the security of the packin p G is a short screw, either cast solid with the stopper and made an integral part thereof or formed separately and cast into the stopper,

(N0 model.)

or otherwise attached so as to form a fixture to the same. It stands up vertically on top, as shown. This screw is threaded with coarse threads, and the bail or yoke O is formed on top with two or more coils, d d, made by bending the wire around a suitable mandrel or form, the coils corresponding in pitch and distance apart with the threads of the screw, and titting into said threads, and forming the nut through which the screw moves in screwing up and down.

Heretofore thumb-screws have been employed turningdown ward and forcing the stopper intoplace. The hearings or nuts through which the screws have passed have been solid and threaded to receive the screws. By coiling the wire bail, as above described, and fitting the coils to the threads of the screw, a good deal of expense is avoided, as the necessity of cutting threads and of using separate crosspieces connecting the vertical sides of the bail is obviated, while a much more compact and effective device is produced. By making the screw solid with the cap the screw and the cap turn down together and the screw moves readily in the coils.

I do not claim, broadly, the use of a screw to force the stopper down; but

I claim-- 1. In a bottle-stopper, the combination of a neck-Wire encircling the neck of the bottle, a bail or yoke pivoted to the neck-wire and ex tending above the bottle, a metallic stopperof the screw and form the not through which the scrcw runs, as herein shown and described. In witness whereof I. have hereunto signed my name in the presence of two subscribing witnesses.
